初三英語虛擬語氣講解及練習(xí)題

1、精選優(yōu)質(zhì)文檔-傾情為你奉上淺談初中英語虛擬語氣的用法一 語氣的概念英語動(dòng)詞不僅有時(shí)態(tài)、語態(tài)等的變化，而且還有語氣的變化。語氣和時(shí)態(tài)、語態(tài)一樣都是英語的語法現(xiàn)象。從形式上看，語氣是動(dòng)詞的一種變化形式。從意義上講，語氣是表示說話人對(duì)某一行為或某一事情的看法和態(tài)度。根據(jù)說話人的意圖，語氣可分3種：直陳語氣（又叫陳述語氣）用來陳述事實(shí)（或提問題）等?？梢杂糜陉愂鼍洌部梢杂糜谝蓡柧浠蚋袊@句。祈使語氣用來提出請(qǐng)求或命令等。主要用于祈使句。虛擬語氣見下面。語氣和時(shí)態(tài)是截然不同的概念，但語氣要通過動(dòng)詞的時(shí)態(tài)形式表示出來。二虛擬語氣概念通常是表示說話人所說的話不是一種事實(shí)，而是一種純粹的假設(shè)、虛擬、主觀愿望或

2、建議等?？梢杂糜陉愂鼍?，也可以用于疑問句等。動(dòng)詞形式虛擬語氣的動(dòng)詞形式大多數(shù)情況是用動(dòng)詞（相應(yīng)）的過去時(shí)（相對(duì)直陳語氣而言）。動(dòng)詞be若用過去式時(shí)可以一律用were。應(yīng)用在含有條件狀語從句的復(fù)合句中的應(yīng)用。表示純粹的假設(shè)，或可能性很小的情況。主從句的謂語動(dòng)詞主要形式如下：從句主句對(duì)現(xiàn)在或?qū)淼那闆r假設(shè)時(shí)過去式would+動(dòng)詞原形對(duì)過去的情況假設(shè)時(shí)had+done（過去完成時(shí)）would+have+done例：1）IfIwereyou,Idwearashirtandtie.2）Whatwouldyoudoifyouhadamilliondollars?3）Ifyouhadcomeafewminu

4、意：我明天根本不可能來這兒，或我明天能來這兒的可能性很?。?）Wewishhehadntgone.他要是沒有走該多好??！用在suggest等的賓語從句中，表是純粹的建議。句型為：suggest(ed)that(should)+動(dòng)詞原形（should可省略）1）Hesuggeststhatwe (should)visitthemuseum.2) Wesuggestedthathe_hereeveryday.A.comeB.comesC.cameD.cancomeE.couldcome虛擬語氣的幾種特殊用法1.省掉if的條件從句結(jié)構(gòu)：Had you asked me, I would have t

7、h, he .)3. 有時(shí)條件從句中的動(dòng)作和結(jié)果從句中的動(dòng)作發(fā)生的時(shí)間不一致，如：If he had followed the doctors advice, he would be quite all right now.If I were you, I would have gone home.五、虛擬語氣的其他用法1、Suggest, advise 等動(dòng)詞之后賓語從句須用虛擬語氣，其句子結(jié)構(gòu)如下：suggest, advise, recommend, demand,require, insist, urge, request, order, +that(should )+動(dòng)詞原形devi

8、de, ask, move, propose等注意：在此結(jié)構(gòu)中that不可省略；should省不省均可。He suggested that they (should ) stop smoking.上述動(dòng)詞的名詞形式出現(xiàn)時(shí)，that 引導(dǎo)的從句仍用虛擬語氣。He made a request that they (should ) stop smoking.如果that 引導(dǎo)的從句所表達(dá)的內(nèi)容是事實(shí)，也可用陳述語氣。He insists that he is right.2、It is (was )+necessary, a pity 等+that引導(dǎo)的從句須用虛擬語氣，其句子結(jié)構(gòu)如下：impe
